In this you can see the future also your Bruce's cousin and you too are affected by the gamma radiation.

I was hanging with my cousin Bruce while playing a video game while Bruce was sitting next to me reading. I made it to a checkpoint when my phone rang. I paused the game and answered the phone. " Hello this is Y/n and at this time my brain has stepped out for the moment so proceed with caution. " I hear a deep  chuckle from the other end. " Hello Y/n its sounds like your well. " I shrug and resume playing Ocarina of time. " I guess hows Tony ? "  Steve went silent . " Steve whats wrong ?" Bruce put down his book down.  " I'm so sorry Y/n I really am ." He started to get me worried and I don't much care for it .  "Steve whats wrong tell me !?" I hear him let out a big sigh . " I have to be honest with you Y/n because I love you .  Y/n I think I may have started a war with Tony . " I let out a breath I didn't know I was holding in . " I told you this would happen is there anything else you want to tell me ?" I already knew what had happen between him and Agent 13 but I wanted him to tell me .  I hear him starting to break down a little . " I didn't mean to Y/n I'm sorry ." Bruce took the controller out my hand and paused the game again. " I...I didn't .... she.... I.. " I still can't believe he cheated. I wiped away the escaping tears. " I remember when you told me that you wouldn't cheat . Just let me guess you enjoyed the kiss didn't you and I bet she was related to Peggy wasn't she !?" I couldn't help myself from getting mad wouldn't you be mad if your boyfriend cheated on you ? Steve started to cry . " I just hope when you started this war Rodgers that you knew what you are getting yourself into."  Bruce looked at me in pity. " I'm sorry I really do love you Y/n ." Steve said pleadingly. " No you didn't Steve not if you cheated." I can't take this conversation. " Good bye Steve."  He started to say something but I hang up. " Y/n are you okay ?" Bruce asked calmly. I get up and throw my phone across the room. "You need to calm down." I can't control it anymore. " I'll be back later Bruce. I can't believe that I thought he was different but their all alike."
